Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00014 | $0.00219 |
| Opus 5 | $0.00007 | $0.00110 |
| Sonnet 5 | $0.00003 | $0.00044 |
| Haiku 4.5 | $0.00001 | $0.00022 |
Grade A, and why
review-crds scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Kubernetes API Conventions Skill
Task
Review any CRDs in Agent Substrate to ensure they follow the conventions in references/api-conventions.md.
Output Format
Your output should be a list of violations conforming to the following JSON format:
[
{
"location": "",
"rule": "",
"fix": ""
}
]
- location: file path and line range that violated the rule, formatted like this:
path/to/file/under/review:1-10. The path is relative to the repo root. - rule: Exact quote of violated rule from
references/api-conventions.md. If there is no rule, this should be set to the stringOPINION. - fix: Your suggestion of how to fix the issue.
Hints
- All CRDs are defined in
pkg/api/v1alpha1.
References
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

review-crds is a skill published in the GitHub repository agent-substrate/substrate (1,703 stars, last pushed yesterday), licensed Apache-2.0. It adds 14 tokens to every session and 219 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
